Local Law 152 Deadlines by Community District: NYC Building Owner Guide

Local Law 152 Deadline Schedule

DOB groups Local Law 152 inspection deadlines by community district. The official schedule works in four sub-cycles, and each sub-cycle repeats every four years.

For the current cycle, buildings in community districts 4, 6, 8, 9, and 16 have an inspection window running from January 1, 2026 through December 31, 2026. Buildings in districts 11, 12, 14, 15, and 17 are due in 2027. The cycle then starts over with districts 1, 3, and 10 in 2028.

How to Find Your Community District

Your Local Law 152 deadline is based on community district, not borough alone. Queens, Brooklyn, Manhattan, and the Bronx each contain multiple community districts, and nearby buildings can fall into different sub-cycles.

1. Look up the building address. Use the NYC Department of City Planning community profile lookup or the DOB property record.
2. Confirm the community district number. The number is the key field for the LL152 sub-cycle.
3. Match that district to the schedule. For example, Community District 6 is a Sub-Cycle C district, so the current window is 2026 and the next one is 2030.
4. Check whether a GPS2 was already filed. Do not assume the filing happened because an inspection was performed. The certification must be submitted.

Austin Plumbing can check your address, confirm the assigned inspection year, and tell you whether the building appears current before the deadline becomes urgent.

Which Buildings Are Covered?

Local Law 152 applies broadly to NYC buildings, with key exemptions for one- and two-family homes and other buildings classified in Occupancy Group R-3. DOB also publishes building classification categories that are not required to comply.

If your building is multifamily, mixed-use, commercial, institutional, or has multiple dwelling units with gas service, assume it may be covered until the record is checked. A building with no active gas service may still need a certification path showing that it contains no gas piping or is no longer supplied with gas.

What Has to Happen Before the Deadline?

The deadline is not just the day an inspector visits. A complete Local Law 152 compliance cycle includes inspection, owner documentation, and DOB submission.

• Inspection by an LMP or qualified individual working for an LMP. The inspection covers exposed gas piping and visible conditions required under the rule.
• Gas Piping System Periodic Inspection Report. The LMP provides the inspection report to the owner within 30 days of inspection.
• GPS2 certification submission. The owner submits the signed and sealed certification to DOB within 60 days of inspection.
• Correction certification if deficiencies are found. If the initial certification identifies conditions requiring correction, the owner must submit a follow-up certification after correction.

Waiting until late December creates a scheduling problem. If the inspection finds deficiencies, you may need corrective work, permits, pressure testing, re-inspection, and a second certification before the record is clean.

What If the Inspection Finds a Problem?

Not every Local Law 152 inspection ends with a clean GPS2. Common deficiency findings include corrosion, unsupported piping, improper fittings, missing shutoff access, non-compliant appliance connections, CSST bonding issues, or evidence of unpermitted gas piping alterations.

Unsafe or hazardous conditions must be reported immediately to the owner, utility, and DOB. That can lead to a gas shutoff until corrective work is completed. Less urgent deficiencies still need to be corrected and certified within the required follow-up timeline.

Recommended Planning Timeline

The best LL152 work happens before the deadline pressure starts. Building owners should plan around the possibility that the first inspection may uncover conditions that need repair.

Multifamily buildings should also plan tenant access early. Inspectors need access to visible gas piping and appliance connections; missed apartments can delay the inspection or require follow-up visits.

Common Deadline Mistakes

• Using borough instead of community district. A Brooklyn building is not simply due when Brooklyn is due. The community district controls the cycle.
• Assuming inspection equals filing. The GPS2 certification must be submitted to DOB; an inspection report sitting in a file is not enough.
• Waiting until the last month. If deficiencies are found, there may not be enough time to correct them before the cycle closes.
• Ignoring buildings without active gas service. Covered buildings without active gas may still need a no-gas certification path.
• Not checking old filings after a purchase. New owners often inherit missed LL152 obligations from prior ownership.

How This Guide Differs from Our LL152 Service Page

This article is a deadline guide. Use it to understand the cycle, community district schedule, and planning timeline. If you are ready to schedule the actual inspection, corrective work, or GPS2 handling, go to our Local Law 152 gas piping inspection service page.

If you already have a DOB violation, Notice of Deficiency, utility shutoff, or failed inspection, the issue has moved from deadline planning into violation response. In that case, start with our DOB plumbing violation removal process or call directly.
